Screenshot Planner

Plan compelling App Store screenshot sequences that showcase your app's value.

When to Use

  • User is preparing App Store assets
  • User wants to improve screenshot conversion
  • User asks about screenshot strategy or captions
  • User is launching a new app or major update

Information Gathering

Before planning, ask about:

  1. App Type

    • What category? (Productivity, Games, Lifestyle, etc.)
    • Primary use case?
    • Visual style of the app?
  2. Key Selling Points

    • What makes users choose this app?
    • Most impressive features visually?
    • Any unique UI elements?
  3. Target Audience

    • Who downloads this app?
    • What problem are they trying to solve?
    • What matters most to them?
  4. Competitors

    • What do competitor screenshots show?
    • How can you differentiate?

Screenshot Strategy

The 5-Screenshot Framework

Most users only see the first 2-3 screenshots. Order matters!

Position Purpose Content
1 Hero Shot Value proposition + best visual
2 Core Feature Primary use case in action
3 Key Differentiator What makes you unique
4 Secondary Feature Another compelling feature
5 Social Proof/CTA Reviews, awards, or final push

Extended (10 Screenshots)

Position Purpose
6 Additional feature
7 Customization/settings
8 Integration/ecosystem
9 Before/after or workflow
10 Final CTA with app icon

Caption Writing

Caption Formula

[Action Verb] + [Benefit] + [Optional Detail]

Examples by Category

Productivity:

  • "Capture ideas instantly"
  • "Never miss a deadline"
  • "Your tasks, beautifully organized"

Health & Fitness:

  • "Track every workout"
  • "See your progress over time"
  • "Personalized plans that work"

Photo & Video:

  • "Edit like a pro in seconds"
  • "Filters that actually look good"
  • "Share anywhere with one tap"

Finance:

  • "Know where your money goes"
  • "Budget without the stress"
  • "Insights that save you money"

Caption Rules

Do:

  • Keep under 8 words
  • Start with action verbs
  • Focus on user benefits
  • Match the visual exactly
  • Use sentence case

Don't:

  • Use technical jargon
  • Include version numbers
  • Mention prices
  • Use "Our app does..."
  • Write full sentences

Visual Best Practices

Device Frames

Approach When to Use
With frames When device context matters, lifestyle apps
Without frames Maximizing screen real estate, content apps
3D angles Standing out, premium feel
Flat/straight Clean, professional, enterprise

Backgrounds

  • Solid colors: Clean, professional, fast loading
  • Gradients: Modern, dynamic, attention-grabbing
  • Lifestyle photos: Context, emotion, aspiration
  • Abstract patterns: Creative, unique, memorable

Typography

  • Use 2 fonts max (headline + body)
  • Minimum 60pt for headlines (iPhone)
  • Ensure readability on small thumbnails
  • Match your app's brand fonts if possible
